'The latter has somewhat the tion engines in which-the mixture of the gas and air form of a ring of rectangular section which leaves free takes place directly on the seat surface of the gasvalve above and below in direct proximity to the seat sur- 10 in order to thoroughly mix the same. According to. faces of the valve' e, an annular narrow slot 7c through this invention this result is attained to an increased exwhich the air enters the mixing chamber at a suitable tent by employing a double seated valve, instead of the speed. I single seated valve employed in the usual forms of confurther advantage is produced by the double seat struction both valve disks of which double seated valve. valve only needing to be lifted half as high, in order to 15 serve exclusively for opening or closing the gas passage. obtain an equal section of passage, as a single seat valve The gas current is thereby divided into two parts and of similar diameter. The smaller however the distance also in consequence of the small apertures of the assage of the valve disk is from the valve seat, the stronger will the formation of eddies is facilitated so that a more the escaping gas be throttled. Therebythe formation thorough mixture of the gas and air takes place than of stronger eddies is facilitated, which in turn substan- 20 where a single seated valve is used.
